Method of preparing keratin fertilizer with an additive of humic acids in colloid form and keratin fertilizer with humic acids additive

ABSTRACT

A method of preparing a fertilizer by feather processing inserts a weighed feather is inserted into a reaction container, and then adds caustic potash. Water is then added, and feather disintegration occurs. Phosphoric acid is poured into the mixture, and then the pH is measured—and if necessary improved with phosphoric acid or caustic potash. Epsom salt, vitriol of iron, boric acid, manganic sulphate, zinc sulphate, cuprous sulphate, ammonium molybdate and calcium nitrate are mixed in, and the mixture is partitioned into transportation containers depending on the weight of caustic potash included in the mixture using a drain pump through appropriate filter under constant stirring. The mixture is diluted with water, and the whole mass is perfectly mixed. Humic acids are then mixed into the diluted mixture to form a final keratin fertilizer with humic acid additive in colloid form.

BACKGROUND OF THE INVENTION

1. Field of the Invention

Invention relates to a method of preparing keratin fertilizer with anadditive of humic acids in a colloid form and keratin fertilizer withhumic acids additive.

2. The Prior Art

A fertilizer additive containing organically fixed nitrogen used forproduction of granulated or liquid fertilizer is described in apublished patent application No PP 1539-2003 in the Slovak Republic.This additive contains a mixture of original non-adjusted cattle hornsand hoofs or adjusted granular form cattle horns and hoofs with humidityup to 12% of the horns or hoofs weight and up to 18% of the content oforganically fixed nitrogen of a protein character while the size ofgranules made from cattle horns and hoofs granules varies from 0 mm to12 mm.

The substance of a given solution is concurrently a method of productionof the fertilizer additive containing organic nitrogen that is used forproduction of granulated or a liquid fertilizer according to which amixture is poured into a technological container, for example into areactor. A 100% caustic potash/KOH/in a mass ratio of a minimum 1:2 isadded into a processed mixture and a content of a technologicalcontainer is filled with 200 liters of water. The mixture can beintermixed or warmed in a lixivium bath. After the mixture is dissolvedit is neutralized by mixing in of 50 liters of 85% phosphoric acid.After the neutralization process is finished, the mixture can beenriched with other nutrients as for example with NO₃, Mg, Fe, Co, B,Mn, Zn, Cu etc. At the end the solvent is mixed with water/H₂O/up to avolume not to exceed 1,000 liters.

The amount of nitrogen in soil is the most important factor from thepoint of view of plant nutrition even though the presence of phosphorusand sulfur has a positive effect to plant nutrition too. The Nitrogen isorganically bound in a soil and therefore it loosens gradually into asoli. It changes primarily to ammoniac form (NH₄)⁺ by the decompositionof albumin substances and by another oxidation it transforms as forth asthe nitrate form (NO₃).

Fertilizers produced so far have usually low amount of nutrients. Thenitrogen is present in a nitrate form and in less significant extentalso in an ammoniac form. Amidic nitrogen functions less necrotic to aplant tissue when it is not applied directly to a root. In a combinationwith other nitrogen forms the amidic nitrogen allows for betterexploitability of this nutritive by plants.

A method for a production of compost according to the Hungarian PatentNo. 205 336A is known as well. This Patent describes a production methodwith high amount of organic substances with stimulative and alternativemelioration effect with use of an additive containing keratin and swinedung. The production process itself is a separation of liquid swine dungwith help of a phase separation into two parts—solid and liquid part.The solid part of dung is mixed with substances including keratin/hair,horns/. The basic material, originating from this process, contains5-50% of keratin substance. Basic material is mixed with 2-8% of hydrantlime, 5-10% of algin, 5-10% of riolit-tufa/sand stone/and 10-20% ofpeat. Acquired mixture, taking into account its total weight, is beinghomogenized with mixing in 10% of keratin additive. Such well mixedcompost is then formed into pits. The humidity of a pit up to 65-80% issecured with a help of a liquid that contains 5-20% of dissolvedkeratin. Such a pit is interblended after expiry time of 1-2 months.

According to a Hungarian patent No. 205 739A a basic substance forslowly degrading bio-fertilizer enriched with trace elements and withhigh amount of organic substances using keratin is known as well. Theproduction process is as follows: substances containing keratin areintermixed with hydrate of lime, and then during a permanent mixing inan autoclave they are undergoing a process of a heat treatment underconcomitant pressure change. A hot mass is filtered and filled in tanks.The mass produced under such procedure and intended for bio-fertilizeris supplemented by trace elements at need.

Mentioned fertilizers with keratin additive are technologicallydemanding, time-consuming and claim for a certain amount of time beforerealization as well as the heat treatment increases the costs for itsdevelopment.

SUMMARY OF THE INVENTION

The subject-matter of the invention according to this patent applicationis a method of preparation of keratin fertilizer with humic acids incolloid form additive and fertilizer produced by this process that isobtained by a feather processing in a poultry processing plant.

Feather delivery in a transport container approved by veterinaryauthority and accomplished by valid disinfection performed by authorizedfirm has to take place before the beginning of a production process.Feather is then batted out on appropriate and especially for thispurpose assigned place. Feather processing starts immediately after thefeather transport to an assigned place in order to avoid any possiblenon desired feather quality changes.

The first step consists of inserting the already weighed feather into areaction container. Such a container must be produced from a materialresistant to concentrated alkalics and be equipped with closingmechanism, mixing mechanism, intake valve, escape valve and must beequipped with self-exhaust mechanism through a carbon filter as well.

In the second step the caustic potash (KOH) in a ratio to the amount ofweighed feather is added into a reaction container already filled withthis feather.

In the third step the water in a ratio to the amount of weighed featheris mixed into a mixture under preparation in a reaction container. It isimportant to close up the reaction container before the water is addedbecause the water has to be added at one bout due to the fact that amixture under preparation heats up intensively.

The fourth step sees feather disintegration in a reaction containerlasting 20 hours. The feather is dissolved in a closed up reactioncontainer under occasional stirring and acting of caustic potash (KOH)in about 20 hours.

In the fifth step 85% phosphoric acid is mixed into a mixture in a ratioto the weight of weighed feather in a reaction container. After thefeather is dissolved, in the fourth step, the mixture under preparationis neutralized by 85% phosphoric acid. This acid is possible to mix indirectly into a reaction container and under intensive stirring of amass in container. A reaction connected with short time bubbling is inprogress still in this fifth step.

A measurement of the acidity or alkalinity/pH measurement/of a mixtureunder preparation begins the sixth step of a process. A trial probe outof neutralized mixture is taken out, chilled to 20% ° C. and its pH ismeasured. Requested pH shall be in a range of 6.5±0.2. In a case of agreater discrepancy it is needed to improve pH with 85% phosphoric acidor caustic potash.

The seventh step includes adding epsom salt, vitriol of iron, boricacid, manganic sulphate, zinc sulphate, cuprous sulphate, ammoniummolybdate and calcium nitrate.

The eight step includes partition of a mixture under preparation fromreaction container into prepared transportation containers. Thepartition depends on a weight of caustic potash included in a mixtureunder preparation. Neutralized mixture under preparation, what is abasis of a fertilizer, is apportioned on the basis of calculation fromthe reaction container into prepared transportation containers with ahelp of drain pump through appropriate filter and under constantstirring of a mixture under preparation/basis of a fertilizer/in areaction container.

The ninth step includes preparation of a diluted mixture underpreparation. Transportation containers are equipped with water-proofclose up mechanism with a possibility of stirring. Water is added intosuch a container with a mixture under preparation and the whole massshall be perfectly mixed.

The tenth step contains mixing in of humic acids into diluted mixtureunder preparation in a transportation container. This process causes aformation of a final keratin fertilizer with additive of humic acids ina colloid form.

Keratin fertilizer with humic acids in colloid form contains feather,caustic potash, phosphoric acid, epsom salt, vitriol of iron, bromicacid, manganic sulphate, zinc sulphate, cuprous sulphate, ammoniummolybdate, calcium nitrate, humic acids and water.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Before the beginning of a production process a feather delivery frompoultry processing plant has to take place in a transport containerapproved by veterinary authority and accomplished by valid disinfectionperformed by an authorized firm. Transported feather is then batted outon appropriate and especially for this purpose assigned place. Featherprocessing starts immediately after the feather transport to an assignedplace in order to avoid any possible non desired feather qualitychanges. Feather is pressed out of a water, what is done standardly inpoultry processing plant and has a humidity at a range from 25% to 29%.It means that, for instance, out of 300 kg of a moist feather deliveredfrom poultry processing plant it is possible to obtain cca 107 kg of adry feather (300:2.8˜107), meaning that in 300 kg of a moist featherthere is cca 193 liters of a water.

In the first step the already weighed feather is inserted into areaction container, where P—is the weight of weighed feather. Such acontainer must be produced from a material resistant to concentratedalkalics and be equipped with closing mechanism, mixing mechanism,intake valve, escape valve and must be equipped with self-exhaustmechanism through a carbon filter as well.
